As

An added feature of the present invention lies l'lustated in Figure 2, the base plate l0 is proin the provision of a fastener having a rotatable Vlded W1th an ear I4 DlOJ'eCting laterally theregagement of the rotary part therewith. However, The base plate l0 is provided with a central the keeper tends to urge the rotary part inwardaperture I 5 therethrough which may be countersunk as indicated at IS in Figure of the drawings. The countersunk portion of the hole is on the under or base surface of the base plate li) and opposite the surface over which the rotary part li is designed to rotate.

The rotary part Il comprises arcuate portion l1 extending than 180 degrees about its center and a blunt pointed projecting end I9 projects sleeve 2t is punched from the axis of the rounded portion l1, the axis of the sleeve being normal to the plane of the rotary part. This sleeve is of proper outside diameter to fit within the aperture l5 in the base plate l0. The extremity 2l of the sleeve 20 is riveted over into the countersunk portion i6 of the base plate so'as to permanently attach the rotary part H to the base plate l0.

In actual practice the construction described is simple toY manufacture and assemble. The sleeve 2o is merely punched from the plate and is drawn into a cylindrical hollow shank projecting ashort distance from the center of the rotary part. By merely extending this sleeve through the aperture and placing the sleeve beneath a spinning tool, the sleeve end may be flared outwardly as indicated in Figure 5, thereby riveting the rotary part to the base plate by allowing sufficient play to permit relative rotation between these parts.

The keeper is indicated in general by the numeral 22. This keeper includes a base portion 23 comprising an elongated strip of metal or the like having punched or pressed therefrom a rounded off-set portion 2li. The off-set portion 2li is rounded in its periphery and the rounded portion is of slightly Vgreater radius than the pointed end i9 of the rotary part l l. Thus whenproperly placed relative to the rotary part Il, the off-set portion 24 will be concentric therewith and will enclose the blunt pointed end I9 of this rotary body.

As indicated in Figure 4 of theY drawings the oli-set portion 24 is provided with a downwardly rounded forward edge, the center portion 25 of a body having an this forward edge being below the level of the end portions thereof. As a result of this construction Ythe pointed end i9 of the rotary part ll can readily enter the off-set portion at the ends thereof, but as this pointed portion is pivoted toward the center of the off-set, additional pressure is exerted against the rotary part. The projecting point lll ,on the base plate l0 supports the rotary part l l beneath the pointed end end is urged rearwardly by the cam shape of the Volf-set portion 2li.

A radially extending slot 26 is provided inthe rotary part Il designed to accommodate the end ofV aV screw driver or By inserting the screw' driver intov properly manipulating the same, the rotary portion ll may be rotated about its axis for engagement or disengagement with the keeper 22.

As'Y indicated in the drawings the keeper 22 is vprovided with spaced apertures 21 at opposite ends of the base plate 23 for accommodatioh'of fastening screws 29 'by means of which the keeper plate may be attached in place.

The fastener is extremely simple in construction and holds the window firmly in place under spring tension due to the ,action of the `cam Vshaped off-set 24 bearing against the rotary part l l. There is sufficient resilience in the keeper to urge the window tightly against its frame. Due

'to the fact that a screw driver or similar ini9 as this pointedV described the principles of modation of a Asaid Velongated aperture guiding the tool strument is used for rotating the fastener, the fastener will not become accidentally disengaged as readily as will turn buttons or other devices previously used. Furthermore, the rotary part Il is spaced from contact both with the window and the frame and thus will not affect the surfaces of these elements in operation.

In Figures 6 and 7 of the drawings I disclose a modified form of fastener which is indicated in general by the letter D. This fastener is identical in operation to the fastener previously described, but is somewhat simpler to manufacture and attach. Only one part of the fastener is illustrated in Figures 6 and 7 as the keeper 22 is used with the fastener in the manner previously described.

The fastener D includes a base plate 3l) which is provided with an integral sleeve 3l at its center point. The sleeve 3l is punched from the body of the plate 30 into tubular form and forms a means of connecting the base plate with the rotatable latch plate 32.

The base plate 3i) is generally circular in shape and is provided with an ear 33 projecting from one side thereof. The ear 33 is designed to extend toward the adjacent edge of the window so as to form the longest possible bearing for the :latch plate 32. The latch plate 32 is provided with a rounded edge 3d having a pointed end 35 projecting to one side thereof. An elongated slot 3G extends radially through the plate 32 directed toward the pointed end 35 thereof.

The base plate 36 is provided with a pair of spaced downwardly extending prongs or lugs `31 which extend into the surface of the window or other element on which the base plate is mounted to'prevent this base plate from rotating. The upper end of the sleeve 3l is riveted over the beveled outer end 39 of an aperture di! through the latch plate 32. The sleeve 3l thus holds the latch plate assembled to the base plate and allows rotation of the latch plate'relative to the base plate.

The sleeve 3l is hollow to `admit a headed screw or similar fastening means used to hold the Vwindow fastener in place.

From the foregoing description it will be obvious that the fastener tener A mainly in the manner in which the vbase plate is connected to the window. In place of extending the base plate and providing spaced screws to hold the same in employs a single screw which extends through the central sleeve and depends upon the prongs 31 for holding the base plate from rotation.

in accordance with the patent statutes, I have construction and operation of my window fastener, and while I have endeavored to set forth the best embodiment thereof, l desire to obvious changes may be made within the `scope Vof the following claims without departing from the spirit of my invention. Y
